Silver Telluride Colloidal Quantum Dot Solid for Fast Extended Shortwave Infrared Photodetector

Yongnam Ahn,
So Young Eom,
Gahyeon Kim
et al.

Abstract: Extended shortwave infrared (eSWIR) photodetectors that employ solution‐processable semiconductors have attracted attention for use in applications such as ranging, night vision, and gas detection. Colloidal quantum dots (CQDs) are promising materials with facile bandgap tunability across the visible‐to‐mid‐infrared wavelengths. However, toxic elements, such as Hg and Pb, and the slow response time of CQD‐based IR photodetectors, limit their commercial viability. This article presents a novel eSWIR photodetect… Show more
